area forecast discussion
national weather service san diego ca
927 pm pdt Thu mar 21 2019

Synopsis
Only isolated showers will occur overnight as an upper level
trough begins to move away from the area. Friday will be dry and
a little warmer. Another low pressure system will moving across
northern and central california this weekend bringing gusty
southwest to west winds in the mountains and deserts and a chance
of light showers over and west of the mountains. Dry and warmer
weather is expected Sunday through Tuesday. The approach of another
storm system will result in a chance of precipitation by mid week.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

the upper level trough which resulted in widespread rain and high
elevation snow over the last couple of days is moving east of the
area tonight. Showers have mostly dissipated this evening and will
keep only 10-20 pops going for the remainder of tonight for some
isolated showers. Expect dry weather on Friday with a return of
some sunshine as well. The next storm system will move across
northern california this weekend with the best dynamics staying
well north of the area. Have only small chances for precipitation
in the forecast for Saturday and Saturday night with minimal
impacts expected.

From previous discussion...

at 1 pm, water vapor satellite displayed an upper-level low
centered over southern nevada. Radar showed a band of mostly
light showers moving southeast across the region, just now
entering san diego county. Additional rainfall through this
evening looks to be lighter than expected, with an additional one-
quarter inch of precipitation possible, and an inch or two of
snowfall expected, mostly above 6500 feet. The winter weather
advisory for the riverside and san bernardino county mountains
continues through 8 pm this evening.

Weak ridging will develop Friday, with dry weather and highs 5-10
degrees below normal. A trough will then move across northern ca
on Saturday. Lack of upper-level dynamics and moisture will limit
shower activity over our area, with only small chances of light
precip over and west of the mountains.

Upper-level heights build early next week, with southwesterly flow
aloft and dry weather across southern ca. Highs will be mostly
near normal Sunday through Tuesday, with Monday and Tuesday being
the warmest days.

On Wednesday and Thursday, models show an upper-level trough
moving across the western states with continuing differences in
the details. The GFS is dry over southern ca, while the ecmwf
generate precip. The current forecast uses a blend, with
increasing chances for precipitation centered around Wednesday.

Snow levels will range from 5000-6000 ft through the period. As
the trough moves inland, there will also be periods of stronger
and gusty southwest to west winds in the mountains and deserts.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
